The glutarimides of the instant invention can be prepared by a two-step sequence starting from an anilino or amino compound of the formula ##STR9## wherein D, T, X, Y, Z and Q are as defined in Formula I above. Compound II is reacted with about an equivalent of a suitably substituted glutaric anhydride having the formula ##STR10## wherein R, R¹ and R² are as defined in Formula I above, to yield a compound having the formula ##STR11##

Examples of suitable solvents for this reaction include ethers, such as ethyl ether, tetrahydrofuran (THF) and glyme; hydrocarbons, such as toluene; acetonitrile; N,N-dialkylamides, such as dimethylformamide; and halocarbons such as methylene chloride and chloroform. A mixture of solvents can be used to achieve homogeniety. The reaction is generally carried out at about atmospheric pressure at a temperature of from about -10° C. to about 100° C. Preferably the temperature employed is in the range of from about 0° C. to about 70° C.

The compound of Formula IV is then cyclized in the presence of acetic anhydride and sodium acetate, or acetyl chloride, or ethyl acetate with thionyl chloride and N,N-dimethylformamide to obtain the desired N-substituted glutarimide (Formula V) of the instant invention. The reaction is generally carried out at a temperature of from about -10° C. to about 250° C. More preferably the reaction is carried out at a temperature of from about 30° C. to about 150° C.

The N-substituted glutarimide of Formula V, ##STR12## wherein Q is not oxygen, can be converted to the thioglutarimide of the invention (Formula VI), ##STR13## for example, by use of a thiocarbonyl conversion agent such as Lawesson's reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide) or phosphorus pentasulfide in the presence of hexamethylphosphoramide or xylenes. The reaction is generally carried out at a temperature of from about -10° C. to about 250° C., preferably from about 50° C. to about 150° C.

The N-substituted glutarimide V (wherein Q is not oxygen) can also be reduced to the corresponding N-substituted piperidine of the invention (Formula VII) ##STR14## using, for example, a reducing agent such as lithium aluminum hydride. The reaction is generally carried out in an aprotic solvent such as ethyl ether or tetrahydrofuran. The reaction is generally carried out at a temperature range from about -20° C. to about 100° C. Preferably the temperature is from about 0° C. to about 65° C.

The piperidones of the invention (Formula VIII) ##STR15## can be prepared by a three step sequence starting from the compound of Formula IV (wherein Q is not oxygen). The glutaramic acid of Formula IV is first reduced to the analogous 5-hydroxypentanamide. For example, a reducing agent such as borane-methyl sulfide complex in a solvent such as tetrahydrofuran or ethyl ether is used. The temperature range is from about -20° C. to about 150° C., preferably from about 0° C. to about 100° C.

The 5-hydroxypentanamide is converted to the corresponding 5-chloropentanamide, for example, by reacting the hydroxy compound with thionyl chloride in an aprotic solvent such as methylene chloride at a temperature range from about -20° C. to about 150° C., preferably from about 0° C. to about 100° C.

The 5-chloropentanamide is then cyclized to the piperidone of Formula VIII, for example, by treatment with base, such as sodium hydroxide in an aprotic solvent such as tetrahydrofuran at a temperature range from about -20° C. to about 150° C., preferably from about 0° C. to about 100° C.

In the case where Z is a substituted carbonyl moiety, the carboxylic acid of Formula V (Z═CO₂ H, wherein Q is not oxygen) can be converted to the corresponding acid chloride (Z═C(O)Cl) by reaction with a chlorinating agent, for example thionyl chloride, in an inert solvent, preferably a hydrocarbon such as toluene or chloroform, at a temperature range between -20° C. and 200° C., preferably from about 50° C. to about 100° C. The acid halide is then reacted with the appropriate nucleophile (for example, alcohol, alkyl mercaptan, amine) in the presence of a suitable base, preferably triethylamine or pyridine, to yield the corresponding compound of Formula I. The reaction is carried out in an inert organic solvent, preferably THF or methylene chloride.

In the case where Y and Z together form a heterocyclic ring, the amino-substituted heterocycle is prepared by means known in the art and then reacted with the requisite glutaric anhydride (III) as described above. Alternatively, when the heterocycle contains a site which can be alkylated, the alkylation can be carried out after the reaction with glutaric anhydride and subsequent cyclization has taken place.

In some cases where Z is a substituted alkoxy moiety, the phenol of Formula V (Z═OH, when Q is not oxygen) is treated with a non-nucleophilic base such as sodium hydride and reacted with an appropriate alkylating agent to yield the corresponding glutarimide. The reaction is carried out in an inert organic solvent, for example, tetrahydrofuran or ethyl ether at a temperature range from about -20° C. to about 150° C., preferably from about 0° C. to about 100° C.

In the case where Z is an oximyl moiety, the benzaldehyde of Formula V (Z═CHO, when Q is not oxygen) is reacted with the appropriate alkoxyamine or alkoxyamine salt in a polar organic solvent such as ethanol at a temperature range from about -20° C. to about 150° C., preferably from about 0° C. to about 100° C. When a salt is used, a base such as pyridine may be added to the reaction mixture.

The starting glutaric anhydrides are prepared as is known in the art, for example, in J. Gootjes and W. Th. Nanto, Rec. Trav. Chem, 80, 1183 (1965). Alternatively, ethyl 4,4,4-trifluorocrotonate and sodio diethyl malonate are reacted in the presence of a catalytic amount of a catalyst such as tetrabutylammonium bromide to yield ethyl 2-(trifluoromethyl)propanetrioate which is in turn treated with a strong base such as potassium hydroxide, preferably between about 50° C. and about 150° C., then acidified and decarboxylated to yield 3-(trifluoromethyl)glutaric acid.

The starting anilino and amino are prepared by known methods, as disclosed for example, in U.S. Pat. Nos. 4,439,229, 4,484,940, 4,484,941, 4,594,099, and 4,640,707, and in PCT/EP87/00279 and PCT/US87/00056 and in the references cited therein.

EXAMPLE A: PREPARATION OF 4-CHLORO-2-FLUORO-5-PROPARGYLOXYANILINE

Into a 300 milliliter (ml), three-necked round-bottomed flask equipped with an overhead stirrer, dropping funnel and thermometer were placed 5-acetamido-2-chloro-4-fluorophenol (21.0 gram (g), 0.103 mole) and dimethyl sulfoxide (DMSO) (100 ml). The mixture was stirred at room temperature and aqueous potassium hydroxide (KOH) (7.0 g KOH, 88% w/w, 1.01 equivalents (eq) dissolved in 10 ml H₂ O) was added dropwise over 10 minutes. An exotherm was noted (25° to 40° C.) during the addition. The solution was stirred for 1 hour, and then a solution of propargyl bromide (80% in toluene, 12.7 ml, 1.10 eq) was added dropwise. An exotherm from 25° to 40° C. was noted during addition. The mixture was stirred at ambient temperature overnight.

In the morning, thin layer chromatography (TLC) (silica gel, 1:1 v/v hexanes/ethyl acetate (EtOAc)) showed that the reaction was complete. The mixture was poured into ice water (600 ml), filtered, washed with water and dried in vacuo at 50° C. overnight to give the expected propargyloxyacetanilide as a tan powder (24.0 g, 96%, m.p. 142°-5° C.).

Into a 250 ml, three-necked round-bottomed flask equipped with an overhead stirrer, thermometer and condenser were placed the propargyloxyacetanilide (9.64 g, 40 mmol), ethanol (absolute, 43 ml), water (56 ml) and concentrated aqueous hydrochloric acid (HCl) (35% w/w, 37.5 ml). A heating mantle was used to heat the mixture to reflux with stirring. After 1 hour at reflux (92° C.), TLC (silica gel, 3:1 hexanes/EtOAc, v/v) of a basified aliquot indicated that the reaction was complete. The mixture was poured into ice water (200 ml) and brought to pH 10 using 50% aq. sodium hydroxide (NaOH) (25 ml) during which time a brown solid precipitated. The mixture was extracted with ether (3×100 ml) and the combined organic layers were washed (2×50 ml water, 1×50 ml brine), and dried over anhydrous magnesium sulfate (MgSO₄). The mixture was filtered, the solvent evaporated in vacuo and dried overnight at 25° C. to give the expected aniline as a brown oil.

EXAMPLE B: 3-(trifluoromethyl)glutaric anhydride

To 115 mg (5 mmol) of sodium metal (cut into small pieces and washed with hexanes) in 5 ml of THF was added a solution of diethyl malonate (800 mg, 5 mmol) in 10 ml THF. The mixture was stirred at room temperature until all of the sodium metal was consumed (2-3 hours). A catalytic amount of tetrabutylammonium bromide was added, followed by a THF solution (10 ml) of ethyl 4,4,4-trifluorocrotonate (0.84 g, 5 mmol). This mixture was warmed to 40° C. and stirred for 17 hours. after cooling to 10° C., glacial acetic acid (300 mg, 5 mmol) was added and the THF was removed in vacuo. The resulting residue was treated with a solution of 87.3% KOH (1.28 g, 20 mmol) in 10 ml water and refluxed for 4.5 hours. After cooling to 10° C., 2.5 ml (26 mmol) of conc. HCl was added dropwise via pipette and the mixture was again heated to reflux until CO₂ evolution had ceased (ca. 1 hour). The solution was cooled to 15° C. and extracted with Et₂ O (3×10 ml). The combined organic phases were dried over Na₂ SO₄, filtered and concentrated in vacuo to afford 3-(trifluoromethyl)glutaric acid as a white solid in 95% yield (m.p. 100°-100.5° C.).

Into a 2 liter 3-necked flask equipped with a mechanical stirrer and reflux condenser were added 320 g (1.6 mol) 3-(trifluoromethyl)glutaric acid and 775 ml acetic anhydride. The solution was refluxed for 2.5 hours and allowed to cool to room temperature. The majority of the acetic anhydride was removed in vacuo (80° C.) to afford a brown solid which was dissolved in 800 ml of CHCl₃ on a steam bath. Following the addition of 200 ml hexanes, a white precipitate began to form. Further crystallization was induced by storage in a refrigerator. The white flocculent solid was filtered and oven dried (50° C., 30 mm Hg) to afford 261 g (89% yield) of the desired product, m.p. 88°-91° C.

EXAMPLE 1: N-(4'-chloro-2'-fluoro-5'-proparglyoxyphenyl)-3-(trifluoromethyl)glutaramic acid

Into a 1 liter three-necked round-bottomed flask equipped with overhead stirrer, dropping funnel, thermometer and nitrogen (N₂) inlet were placed 3-(trifluoromethyl)glutaric anhydride (18.2 g, 0.100 mol) and methylene chloride (CH₂ Cl₂) (250 ml). The mixture was stirred to homogeneity and a solution of 4-chloro-2-fluoro-5-propargyloxyaniline (19.9 g, 0.100 mol) in CH₂ Cl₂ (50 ml) was added dropwise over 10 minutes to give a clear solution. The mixture was stirred overnight at ambient temperature, during which time a thick white precipitate was formed.

To a solution of N-(4'-chloro-2'-fluoro-5'-hydroxyphenyl)-3-(trifluoromethyl)glutarimide (1.64 g, 5.05 mmol, Compound 19) in about 20 ml of methylene chloride was added via syringe nearly 2.5 eq. of pyridine (1 ml) which had been freshly distilled from CaH₂. Then a solution of benzenesulfonyl chloride (0.64 ml, 5.0 mmol) in 4.5 ml of methylene chloride was slowly added dropwise to the reaction mixture with ice bath cooling. The reaction mixture was allowed to warm to room temperature and stirred for 12 hours. Then there was added 0.17 g of additional glutarimide and the reaction mixture was stirred at room temperature for an additional 12 hours. The reaction mixture was poured into 50 ml of water and the layers were separated. The organic layer was evaporated in vacuo and the residue was dried in the vacuum oven (20-50 Torr, 50° C.). The resulting brown solid was rinsed with approximately 5 ml of methylene chloride and suction filtered to yield 1.9 g (82% yield) of the desired product as an off-white powder (m.p. 214°-215° C.).

Using substantially the procedure described in this example, Compound 190 was prepared except ethanesulfonyl chloride was used in place of benzenesulfonyl chloride.

EXAMPLE 5: N-(4'-chloro-2'-fluoro-5'-isopropyloxyphenyl)-4-(trifluoromethyl)-2-piperidone (Compound 14)

a. N-(4'-chloro-2'-fluoro-5'-isopropyloxyphenyl)-5-hydroxy-3-(trifluoromethyl)pentanamide

The temperature was maintained at 10°-20° C. with an ice bath while vigorous bubbling was evident. The mixture was allowed to warm slowly to room temperature and stirred 150 hrs while kept under nitrogen, heated to 55° C. for 6 hours, then cooled to room temperature and allowed to stand for 16 hours. The flask was cooled in an ice/water bath, then 7 ml of methanol (MeOH) were added slowly via addition funnel. The reaction mixture became too thick to continue stirring. It was allowed to warm slowly to room temperature, when the stir bar was again able to stir the mixture. The MeOH and THF were removed in vacuo (20-50 Torr) and the residue was flash chromatographed (2"×7" column, 3:1 hexanes/ethyl acetate, 75 ml fractions). Fractions 18-45 were combined and the solvent was removed in vacuo. The residue was dried in vacuo at 50° C. to yield 1.66 g (39% yield) of the pentanamide as a nearly colorless oil.

b. N-(4'-chloro-2'-fluoro-5'-isopropyloxyphenyl)-5-chloro-3-(trifluoromethyl)pentanamide

To a solution of N-(4'-chloro-2'-fluoro-5'-isopropyloxyphenyl)-5-hydroxy-3-(trifluoromethyl)pentanamide (1.2 g, 3.2 mmol) in 100 ml methylene chloride, was added thionyl chloride (0.24 ml) in one portion via pipette. The solution turned brown. It was heated to 40°-50° C. for about 7 hours, kept at room temperature for 64 hours, heated to 40° C. for 3 hours, then stirred at room temperature for 18 hours. Then additional thionyl chloride (0.1 ml) was added and heating to 40° C. was resumed for about 4 hours. The reaction mixture was cooled to room temperature and the solvent was removed in vacuo. The residue was dried in vacuo (50° C.) and the resulting golden brown, semi-solid mixture was purified via flash chromatography (20 ml fractions, 2'×7' column, 1:9 ethyl acetate/hexanes) to yield a brown solid, m.p. of 57°-63° C.

c. N-(4'-chloro-2'-fluoro-5'-isopropyloxyphenyl)-4-(trifluoromethyl)-2-piperidone

The mixture was heated to 50° C. while stirring vigorously. After 6 hours the reaction was allowed to cool to room temperature, stirring was stopped and the aqueous layer was removed. The organic layer was evaporated in vacuo, then the residue was taken up in ether (50 ml), washed with water (2×50 ml) and then brine. The original aqueous layer was extracted with a second 50 ml portion of ether, the combined organic layers were washed with brine (50 ml) and dried (MgSO₄). The solvent was removed in vacuo to yield 1.3 g. of a brown solid which was recrystallized from hexanes to yield 0.81 g (64% yield) of a brown solid (m.p. 98°-102° C.).

EXAMPLE 6: N-(4'-chloro-2'-fluoro-5'-propargyloxyphenyl)-4-(trifluoromethyl)piperidine (Compound 15)

Into a three-necked round-bottomed flask were placed 0.56 g (15 mmol) lithium aluminum hydride and 60 ml tetrahydrofuran. A thimble containing 3.60 g (10.0 mmol) of N-(4'-chloro-2'-fluoro-5'-propargyloxyphenyl)-3-(trifluoromethyl)glutarimide was placed in a Soxhlet extractor and attached to the reaction flask. The oil bath was heated to 85° C. and 11 ml THF and 25 ml ether were added. After six hours the majority of the glutarimide had been extracted into the reaction mixture producing a grey solid in the reaction flask which prevented stirring. The reaction mixture was allowed to cool to room temperature. Water (0.56 ml) was added slowly followed by 15% NaOH (0.56 ml). Then additional water (1.68 ml) was added in order to precipitate lithium salts. The mixture was suction filtered and the solid was rinsed with ether. The filtrate was evaporated in vacuo to yield 3.4 g of a brown oil. The oil was chromatographed (silica gel, 3:1 hexanes/methylene chloride) to yield 100 mg (3% yield) of the desired product as an oil.

The mixture was stirred to homogeneity and thionyl chloride (99+%, 3.87 ml, 2 eq) was added via syringe, followed by 0.25 equivalent of anhydrous N,N-dimethylformamide. The reaction was heated to about 80° C. for approximately 6 hours, and then allowed to stand overnight at room temperature.

The reaction mixture was poured into 125 ml water and was extracted twice with a total of 100 ml of EtOAc. The organic layers were combined, then washed two times with 100 ml of water and once with 50 ml of brine. The organic layer was separated, dried with MgSO₄, evaporated under reduced pressure, and dried in vacuo (20-50 Torr, 50° C.). The residue solidified on sitting to yield 8.6 g (99% yield) of the glutarimide as a dark brown solid, m.p. 112°-114° C.

The reaction mixture was suction filtered through a short pad of neutral alumina and rinsed with 30 ml EtOAc. The filtrate was evaporated in vacuo and the residue was dried in the vacuum oven for 12 hours (20-50 Torr, 50° C.). The resulting oil was vacuum distilled (2-10 Torr, 70° C.). The residue was chromatographed (silica gel, 1:1 hexanes/methylene chloride) to yield 350 mg (23% yield) of the desired product as a white solid, m.p. 108°-109.5° C.

Using the procedure as used in this example, Compounds 53, 54, 55, 73, and 76 described in Table I were also prepared except the appropriately substituted alkyl halide (eg., benzyl chloride for Compound 73) was used in place of the chloromethyl phenyl sulfide.

A white precipitate began to form as the reaction mixture was allowed to warm to room temperature. The suspension was stirred at room temperature overnight, forming a thick white slurry. The reaction mixture was partitioned between water (50 ml) and ethyl acetate (50 ml) and the layers were separated. The aqueous phase was extracted with ethyl acetate (3×25 ml) and the combined organic layers were washed (1×25 ml sat'd NaHCO₃, 1×25 ml brine) and dried over MgSO₄. Concentration afforded 3.1 g of an orange-brown solid which was passed through a silica gel column (100 g) with 50% ethyl acetate/hexanes.

The compounds of the present invention are broad spectrum herbicides and may be advantageously employed to control selectively monocot and/or dicot weeds in agronomic and horticultural crops, forestry, orchards, turf, vines or for total weed control.

The compounds of the present invention are selective or non-selective, depending on the rate applied, the combination of plants to which they are applied and whether they are applied pre- or postemergent. Such variables are understood by those skilled in the art. At higher dosage rates they tend to be non-selective, while at lower dosage rates they tend to be selective. For example, the ether and thioether glutarimide compounds described above are active both preemergence and postemergence and have shown postemergent control of dicots in wheat; the ester glutarimides have shown preemergent and postemergent control of monocots and dicots, generally requiring lower doses to control dicots than to control monocots; and the heterocyclic glutarimides have shown selectivity preemergence and/or postemergence in crops such as, but not limited to, wheat, corn, rice, soybeans, sunflower, peanuts and cotton.

The present glutarimides may be applied in any amount which will give the required control of the undesired plants. Generally a rate of application of the herbicides of the invention is from about 0.0001 to about 12 pounds per acre and preferably from about 0.001 to about 5 pounds of the glutarimide compound per acre. Most preferably a rate from about 0.002 to about 2 pounds of the glutarimide per acre is used.

The compounds of the present invention are useful both as preemergence and as postemergence herbicides. Preemergence herbicides may be applied to the soil surface or incorporated into the soil. Postemergence herbicides are those which are applied after the plants have emerged and during their growth period. The glutarimides of the present invention may be applied to the soil surface prior to plant emergence or incorporated into the soil or other growth medium prior to planting. This incorporation can be carried out by any convenient means, including by simply mixing with the soil, by applying the glutarimide to the surface of the soil and then disking or dragging into the soil to the desired depth, or by employing a liquid carrier to accomplish the necessary penetration and impregnation.

A glutarimide of the present invention can be applied postemergence to the growth medium or to plants to be treated either by itself, or, as is generally done, as a component in a herbicidal composition or formulation which also comprises an agronomically acceptable carrier. The concentration of the glutarimide in the herbicidal composition can vary from about 1% to about 98%.

By agronomically acceptable carrier is meant any substance which can be used to dissolve, disperse or diffuse a herbicidal compound in the composition without impairing the effectiveness of the herbicidal compound and which by itself has no detrimental effect on the soil, equipment, crops or agronomic environment. Mixtures of the glutarimides of the present invention may also be used in any of these herbicidal formulations. The herbicidal compositions of the invention can be either solid or liquid formulations or solutions. For example, the glutarimides can be formulated as wettable powders, solutions, emulsifiable concentrates, dusts, granular formulations, aerosols, water dispersable granular formulations or flowable concentrates as is known to one skilled in the art. In such formulations, the compounds are extended with a liquid or solid carrier and, when desired, suitable surfactants or emulsifiers are incorporated. Examples of solvents which are useful in the practice of this invention include water, alcohols, ketones, aromatic hydrocarbons, halogenated hydrocarbons, dimethylformamide, dioxane, dimethyl sulfoxide and the like. Mixtures of these solvents can also be used.

It is usually desirable, particularly in postemergence applications, to include adjuvants such as wetting agents, spreading agents, dispersing agents, sticking agents, adhesives and the like, in accordance with agricultural practices. Examples of adjuvants which are commonly used in the art can be found in the John W. McCutcheon, Inc. publication "Detergents and Emulsifiers Annual."

The glutarimides of the present invention can also be mixed with fertilizers or fertilizing materials before their application. In one type of solid fertilizing composition in which the glutarimides may be used, particles of a fertilizer or fertilizing ingredients, such as ammonium sulfate, ammonium nitrate or ammonium phosphate can be coated with one or more of the glutarimides. The solid glutarimide and solid fertilizing material may also be admixed in blending or mixing equipment, or they can be incorporated with fertilizers in granular formulations. Any relative proportion of glutarimide and fertilizer can be used which is suitable for the crops and weeds to be treated.

The glutarimides of the present invention may be applied as herbicidal sprays by methods commonly employed, such as conventional high-gallonage hydraulic sprays, low gallonage sprays, air blast spray, aerial sprays and dusts. For some applications two or more of the glutarimides of the instant invention may be combined, thereby providing additional advantages and effectiveness. When mixtures of the glutarimides of the invention are used, the relative proportion of each compound used will depend on the relative efficacy of the compounds in the mixture with respect to the plants to be treated.

For some applications, one or more other herbicides may be added to the glutarimides of the present invention, thereby providing additional advantages and effectiveness. When mixtures of herbicides are employed, the relative proportions which are used will depend upon the relative efficacy of compounds in the mixture with respect to the plants to be treated. Examples of other herbicides which can be combined with the glutarimides of the present invention include:

The following test procedure was employed. Seeds of selected plants were planted in flats or pots. For preemergence tests, immediately after planting, the test compound was sprayed directly onto the soil surface. The flats or pots were then watered by overhead irrigation. For postemergence tests, the seeds were allowed to germinate and grow for 10 to 21 days. Each series of test plants were selected for uniformity, size and stage of development. The test plants were then treated with the test compound. The plants for postemergence tests were watered by subirrigation only.

The compound to be evaluated was dissolved in an appropriate solvent, usually acetone, and sprayed over the flats or pots using a carrier volume equivalent to 25 or 50 gallons per acre at the rate of application in pounds per acre (lb./A) specified in the table. About ten to twenty-one days after application of the test compound, the state of growth of the plant was observed. Each species was evaluated on a scale of 0-100 in which 0 equals no activity and 100 equals total control. The following tables (Tables VI and VII) shows the results obtained for the test compounds at the stated rate of application.

The glutarimide compounds of the instant invention are also useful as algicides. The compounds may be advantageously used to either prevent or control the growth of algae. The exact amount of glutarimide required will, of course, vary with the medium being protected, the algae being controlled, the particular glutarimide being employed and other factors known to one skilled in the art.

The glutarimides of the present invention, when used for the control of algae, can be used in any of the types of formulations disclosed above for the control of undesired plants. These formulations include liquid solutions, such as emulsifiable concentrates and dilute sprays, and dry powders such as wettable powders and dusts.

The algicidal and algistatic activities of the compounds of the instant invention were determined by the following procedure.

In separate wells of a microtiter plate (Plate A) were placed 100 μl serial dilutions of the compound to be tested in modified Allen's medium, described below. In addition, one well contained only modified Allen's medium (no compound) as a control. Each well of the plate was then inoculated with a mixed algae culture. After 4 hours, a 5 μl aliquot of each well was removed and placed in a different microtiter plate well (Plate B) containing 100 μl of Allen's modified medium. The plates were covered with clear plastic lids and placed in a clear plastic bag along with several moistened paper towels to create high humidity and prevent evaporation from the plates.

The plastic bags containing the plates were placed in high light conditions (200-700 foot candles) at room temperature. After 5 or 14 days the minimal inhibitory concentration (MIC) needed to inhibit growth was determined from Plate A. The effect of inhibiting growth is defined as the static effect. After 8-10 days, the 4-hour cidal effect (killing of the organism) of the compound was determined from Plate B. To read the microtiter plates for static or cidal activity, a stereoscope was used at low magnification to observe growth or no growth in each well. Plate readers were also used to read growth or no growth.

The following procedure was used to prepare modified Allen's medium.

Seven stock solutions were prepared as follows:

Each of the above stock solutions was filter sterilized.

To 940 ml of sterile deionized water, was added 1 drop of the FeCl₃ solution and 10.0 ml of all the other stock solutions. The ambient pH of this medium was about 6.1 and the water hardness was about 65 ppm, expressed as calcium carbonate. The pH and hardness was adjusted to the pH value of Table VIII with sterile 1 normal (N) KOH or HCl for pH and the water hardness of Table VIII with a sterile NaHCO₃ solution (56.03 g NaHCO₃ in 1.0 liter of boiled and distilled water, then filtered and sterilized.

The mixed algae culture was obtained from an industrial cooling tower in Spring House, Pa. and maintained in the laboratory by means commonly known. The mixed culture contained green algae and blue-green bacteria.

The algicidal activity (in ppm) of compounds of the present invention in modified Allen's medium under 750 foot candles of light is shown in Table VIII.
